CVE-2026-53163

The CVE concerns the Linux kernel rtmutex path: specifically, a vulnerability in remove_waiter() that could dereference a waiter not enqueued, triggered via FUTEX_CMP_REQUEUE_PI. The issue is tied to task_blocks_on_rt_mutex() not arming the waiter on deadlock detection, leaving waiter->task NU...
